Very user friendly. The initial set up followed the instructions precisely! Buttons are easy to manipulate. Love that it saves for 7 days. Very motivational. This was bought by our company for a wellness challenge and it's been very successful with most participants.I would give this a 10 except for the fact that I keep losing it. Doesn't stay on a belt loop very well. I am using the cord "fail safe" but sometimes I look down and it's just dangling- where it's not registering steps.
